GEORGE c. BA'J'JZ, or '1i-oraria, .Kansas insane j steine therewith.

A still further object of my invention is to provide a block Jfunctioning as a seat for the adjacent ends of the springs and adapted to remain in proper working relation having guiding means and engaging the leaves reducing the maximum span automatically.

These and other objects will be hereinafter more tully explained.

Referring to the drawings.

Fig. 1 is a top view of a pair ot springs tnnctioningvas a unit.

Fig. 2 is a side view of the spring..

Fig. 3 is an enlarged detailed view of one end of the springs the seat block being in section.

Fig. 4C is a cross section of the block taken on line Ll-l as shown in Fig. 5 looking in the direction of the arrows.

Fig. 5 is a plan view of the block.

Fig' 6 is an edge view. partly in section being taken on line 6-6, looking inthe direction of the arrows in Fig. 5,.

Fig. '7 is a detailed view of one end of one of the inside leaves of the spring, part in section.

ln Figure l is shown two springs centrally connected by clips l and the -ends thereof engaging in blocks 2, the said blocks having side and end walls 3. functioning as guides for the ends of the springs. 5 is the body of the block, having a plurality oie pertorations 6 positioned therein. 7 is a web functioning as a separator for the springs, said separator being integral with the body and walls oi, the blocks, 8 is a laterally extending portion of the body functioning as a bearing on which the springs will rest when compressed to their. ma-Ximum, and along the angle from the ridge 9 to the depth of the depressions as at 10 will be the engaging points for Jthe minimum load.

` The 'ends of the inside spring leaves 511 have a plurality ot bosses i2A and '1241, said bosses adapted to seat in apertures 6 uncf tioning'as guiding means for blocks 2 hol ing said blocks iii alignment with the `ends of the spring leaves for proper engagement during the reciprocations of said springs It will be understood that when bosses l2 enter their respective `apertures the leaf springs 11 will engage on the bearing` 8 Jfunctioning asa ulcrum point for the outer ends of the spring leaves. It is then possible that bosses l2 will di'sengage from their respective apertures and in such case the bosses l2 are relied upon to retain the block in its proper positionrelative to the ends of the spring'leaves.

The said bosses are made by compressing the spring member as shown in Figure 7,v

byr this process the leaf of the spring' is not weakened and it is also means for eliminating the use of shackles, bolts, and eyes formed by the leaf all of which tends to shorten the duration of the springs. The leaves of the spring are heldin alignment by means of the clips l and at the ends by means of the blocks 2, and by detaching clips l any one oit' the leaves of the spring can be removed, repaired and replaced without disturbing other parts of the spring unit. n

Nhen the spring is normally engaged, the ends of the second leaves of each halt as at B engage on the adjacent inside springs over the ridges 9 and the third leaves of each lial'f as at C engage over the laterally eX- tending portions 8, the latter being a protection for the two plies of the springs under maximum load engagement, therefore it is easily discerned how the span of my elliptic spring is diminished in its bearing points automatically increasing the resilient strength as the load is imposed thereon.v

Such modifications may be employed varying the shape and the position of the apertures and likewise the bosses engaging therein, andalso variation of the width of the block vfor varying the distancefolt the been ing points relative tothe span of the springs or other modifications that lie within the scope of the appended claim and having thus described my invention whatl claim as new and desire to secure `by Letters Patent is f n In a spring, springs comprising two halves the said halves comprising a pluralty of leaves, two bosses. 0n. each end of the inside leaves of said springs, said bosses being separated and in longitudinal alii-gnment with their respective: leaves, blocks engaging between the ends of tlie halves of said springs, the said blocks having` ridges near the outside thereof.y apertures pass-ing through the apex of said ridges,Y said apertures adapted to receive the outside bosses on. the ends of said spring leaves as securing means for pivotal engagement of said leaves on the apex of said ridges, laterally extending members on the inside edges of said blocks, apertures cutting into the sides of .said members, said apertures adapted to re- Ceive the inside bosses on the ends of said spring leaves as securing means for pivotal engagement of said springs on said laterally extending members, for the purpose set forth and described.
